My experience with this kind of homework question is that we will never hear from you again. If you can still hear US, then at least hear this: Even if someone were to take the bait this time and do your work for you, your approach does not give me much hope that you will succeed in this field---with or without whatever degree or certificate you are pursuing.
If you do respond back, please tell us if you bothered to try any of the exercises you listed.
